306-018-521-104

Edgeboard Connectors Overview

The EDAC Inc. 306-018-521-104 is a dual female card edge connector designed for through-hole mounting. It features 36 positions arranged in two rows with a 0.156-inch (3.96mm) pitch. The contacts are made of copper alloy with a gold finish thickness of 10.0µin (0.25µm). The insulator is black thermoplastic polyester, rated for operation between -40°C and 105°C. Compatible with card thicknesses from 0.054 to 0.070 inches, it utilizes cantilever contacts and includes flange features for panel mounting.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to ensure correct pin count, termination style, and plating specifications. Confirm that the required card thickness falls within the specified operational range of 0.054 to 0.070 inches. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure mounting hole dimensions align with the provided flange specifications before ordering.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with a 0.156-inch pitch is required for robust mechanical stability. The through-hole termination offers superior durability compared to surface mount alternatives for high-vibration applications. Consider the operating temperature range of -40°C to 105°C for harsh environment suitability. Evaluate the need for side-opening flanges to facilitate installation in confined spaces.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series of card edge connectors, which are engineered for high-density interconnect solutions. The series provides various configurations to accommodate different industry standards and mechanical requirements. Components in this family typically feature standardized dimensions to ensure compatibility with existing chassis and panel designs across multiple electronic sectors.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC models within the 306 series offering identical pitch and position counts. Verify cross-compatibility with third-party connectors by matching critical dimensions such as pitch, height, and contact type. Ensure any alternative maintains the same thermal rating and material composition for equivalent performance.
